IMinovlimal'v'r IN MovABLE SUGAR-CARRIERS.

Specification forming part of Letters Patent No. 173,038; dated`February l, `1876 application led .A

Augustealevaf l To fall whom it may concern: l

Beit known that I, ARCHIBALD MITCHELL, a resident of the city of NewOrleans and State ofLouisiana, have invented a certain new and usefulImprovement in Movable Carriers; and I do hereby declare the followingto be a full, clear, and correct description of the same, ref- Y erencebeing had to the annexed drawing making a part of this specification. l

My invention relates to the construction and arrangementof a movablecarrier, which is de-` signed 'lnore especially for use in connectionwith the apparatus and machinery 'employed in the Robert diffusionprocess for extracting saccharine matter from sugar-cane and otherIsubstances, and thereby Vsimplify and reduce the cost of working thesame. Y

This movablecarrier differs from all others* with which I am acquainted,inasmuch as it will discharge its load at various points of delivery atthe discretion of the operator.v also capable of delivering from eitherend, as will hereinafter be described. l

My invention will be readily understood by referring to the drawing,whereon- Figure l is Va frontelevation, Fig; 2 a rear elevation, and

Fig. 3 a top view or plan, of the same.

A is a substantial frame of timber, mountedthe carrier B.-

Upon what I shall designate as the front ends 0f the shafts b b isrigidly keyed or otherwise secured the, bevel wheels ol d', which arealternately operated by their pinions e c', the

two latter loosely fitted upon the horizontal shaft D, the ends of whichare provided with sleeves f, having an endwise movement upon andrevolving'with the said shaft in the bearings of the brackets f( f',secured to the up- The inner e`nds of these sleeves are provided with Itisconical heads made to t intdrecesses'sunk into the rear ofthe pinionsc e', so that either` 'of the said pinions may', by friction, be throwninto gear by simply turning the nut g upon its end of the shaft D untilthe said nut presses the cone of the sleeve with which it is broughtY incontact into the recess of its pinion, driving the latter forward untilvits teeth engage those of its bevel-wheel. -To prevent the pinions c, cbeing 'pressed too far forward the shaft D is provided` with collars, asat t' t',

Thewheels a of the carrier-frame rest and are operated upon a pair ofrails, h h', both f which are securely fastened upon a bed-plate orplatform, la, to which is also secured, at a point-about half -waybetween the distance traversed by the frame A, a stand, E, whichconsistsof a base-plate, l, and two uprghts, a u. The tops of thel latter are ona line with the center of the horizontal shaft D, upon which is looselytt-ed,'between the upright's of the stand, a cog-wheel, o, the hu'b ofwhich is made sufficiently long to fill up the space between the twonprights of the stand, in order that'it may not have any lateral play.In the said hub is tapped a set-screw, the end or point of whichenters-a keyway or groove, 2,

that is cut the whole length of the shaft D, so-

that, while the said shaft may move freely back and forth in thecog-wheel, the rotary motion of the latter willr be imparted to theformer, and, throughits end gear, operate the carrier B.

Near the outer'edge ofthe top of the uprights m n is a second set ofbearings for the reception of the journals of the main shaft, which isprovided between the uprights with, a pul ley, p, and pinion q, thelatter imparting motion to the cog-wheel o through an intermediatepinion, r, fitted to an independent shaft. .l

z of the latter, to a cog-wheel, 1, located between the tracks. Thiscog-wheel, engaging a rack, 3, secured on a central line to the bottomof and running the whole length of the fra-nie A enables the latter tobe moved back` and forth whenever desired.

At Fig. 2 a means is shown by which the frame A may be moved by handindependently of the gearing heretofore described. It con- Sists of acog-Wheel, 4, which runs loose on a pin, 5, secured to the side ofthemovable frame. The teeth of this wheel mesh into a rack, 6, fastened tothe side of one of the rails, as shown.

Motion isimparted to this wheel from the handwheel 7 through a pinion,8, which is secured upon the inner side of the said hand-wheel, the

two latter running loosely upon a pin, 9.

The shaft D is prevented from bending or springing at its center by thesupporting-arms l0 11, secured to verticalshafts 12 13, the ends ofwhich operate in boxes 14 15 that are secured to the front of thecarrier-frame A, as shown. The hubs of the supporting-arms 10 11 areprovided in their rear with, short arms,

to which is secured, as shown indotted lines at Fig. 3, the ends ot'aconnecting-rod, 16, in

order that the movement of the one will be dependent upon that of theother.

The operation of this portion of my invention will be better understoodby supposing the carrier-frame A to be moving in the direction shown bythe arrow 17. As soon as the supporting-arm 10, which is shown asprojecting outward, is brought in contact with the carrier, B, andwheels a a', 85e., as and for the purposes herein stated.

2. The horizontal shaft D, provided with keyway 2, pinions e e', sleevesf f, brackets ff, nuts g" g, and collars t' i', in combination with thebevel-wheels d d', carrier B, and

frame A, the whole being arranged to operate as and for the purposesherein set forth.

3. In combination with the horizontal shaft,

D, the keyed cog-wheel 0, driving-pulley p,

. and intermediate pinions q and r, all arranged to operate the carrierB, as herein stated.

4. In combination with the frame A and rack 3, the gearing-stand E,lever w, coupling fv, bevel-pinionss t t w y, vertical shaft u, andhorizontal shaft z and cog-wheel 1, allarranged to operate as hereindescribed.

' 5. The reversible supports 10 1l, constructed and applied to the frameA, so as to operate in the manner herein described.

6. In combination with the frame A, the hand-Wheel 7, pinion 8,cog-wheel 4, and rack 6, all arranged to operate as and for the purposesherein speciiied.
